About This Item

This SAE Recommended Practice covers the wiring and rectangularly shaped connector standards for all types of trailers whose gross weight does not exceed 4540 kg (10 000 lb). These trailers are grouped in SAE J684 with running light circuit loads not to exceed 7.5 A per circuit. This document provides circuits for lighting, electric brakes, trailer battery charging, and an auxiliary circuit color code and protection for the wiring from hazards or short circuits. Color code is compatible with SAE J560 and ISO 1724-1980(E). This SAE Recommended Practice is being stabilized because it covers technology, products, or processes which are mature and not likely to change in the foreseeable future.
